Weird annoying little problem

[MrFast4Ward]

Background:

So for Christmas I got the Sirius S50 from my wife. I love it, and I got it hooked up to the car via FM transmitter. It can get annoying, specially in LA when I get bad signal because every other frequency is taken up.

I decided to get an interface that lets me use the CD changer control and turns the wires into an RCA input. The wires go through a box and then have the RCA's on the other end.

I hooked everything up this weekend and I started to get that bad-ground whine from the speakers that matches the RPM's. I tapped the ground from the stereo (brown wire) for that ground. Today, I tried grounding to chassis and it is still whining. I went back up to grounding from the stereo and decided that I need a ground loop isolator to get rid of that whine.

The annoying problem:

Now, every time I hit the "lock" button on the key fob, there is no horn "beep" like before.

Any ideas as to what could have caused that?

Thanks

Enrique-

well you've already figured out the first problem, in that you need a ground loop isolator.

with the horn beep, or lack thereof i should say, that would imply the alarm isn't being set. If you have a VAG, check out the readings in your central convenience module to make sure there are no codes thrown and also that all the sensors are reading correctly.

If you don't have a VAG I can help you out, but you could also make sure the alarm is actually setting. Lock the car with all the doors, and hood, shut completely. Your red locked light should be blinking. Try opening one of the doors from the inside to see if the alarm goes off. If it doesn't, make sure your alarm horn is still working by setting off your panic alarm.

I'm sure someone else will probably chime in with better advice, but I think that would be a good troubleshooting start until then. ;)

If you need a VAG, I've got one.

I'll troubleshoot it in the morning.

I should have also mentioned that I have a timer set at 30 seconds and whenever I turn it off without letting it run the full 30 secs it doesn't like it very much and causes the same problem, even though the alarm is set. :doh:

Thanks again.

OK, Panic button works fine, locked myself in the car and opened the door and the alarm went off. Me = puzzled. Still haven't hooked up the Vag
